PUMP.

SPECIFICATION forming part of Letters Patent No. 300,623, dated June 17,1884.

Application filed December 20, 1883. (No model.)

To all whom it may concern.-

Be it known that I, ELI A. MILLER, a citizen of the United States,residing at Conneaut, in the county of Ashtabula and State of Ohio, haveinvented certain new and useful Improvements in Pumps; and I do declarethe following to be a full, clear, and exact description of theinvention, such as will enable.

others skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters and figures of reference marked thereon, which form part of thisspecification.

My invention relates to improvements in pumps, and has for its object toprovide devices whereby pure air is supplied to the well simultaneouswith the operation of the pump, as will be hereinafter more fullydescribed and claimed. I

- In the drawings, Figure 1 is a front view of my pump. Fig. 2 is avertical section of the pump and well. Fig. 3 is a vertical section ofthe pump on about line an ac, Fig. 1.

The well A is provided with a cover, A, and its water-line isrepresented at A Fig. 2. The pumpstock B extends through the cover, andits lower end is arranged below the water-line of the well. This stockis provided with a sucker, 0, having rod 0, the up per end of which isconnected with the inner end of the handle D. This'handle is pivoted inthe pump-stock, as is usual, and serves to operate the sucker, andthereby raise the water. The stock is provided with a suitable spout, E.An air-cylinder, F, is arranged alongsidethe stock B, with its lower endbelow and-its upper end above the cover A. At the lower end of thecylinder I arrange a valve, F, as clearly shown in Fig. 2. A pipe, F, issecured on the lower endof the cylinder, and depends therefrom into thewell, with its lower end terminating a short distance above thewaterline. The piston G is arranged and operated within the cylinder. Asuitable valve, G, is arranged in thepiston, so as to permit air to passthrough the latter in its upper stroke into the cylinder F. Theconnecting-rod H has one end secured to the top of the piston, and itsother orupper end connected with the handle 1). The escape pipe I isarranged on the rear side ofthe stock B, and extends above and below thedle is operated air is forced by piston G through cylinder F and pipe Finto the well. This pipe F terminates close above the water-line, anddoes not extend into the water,

so that the fresh air circulates freely above the water and passes outthrough pipe I.

This circulation of fresh air and expulsion of 65 the foul air in thewell takes place simultaneous with the operation of pumping, andtherefore cannot be overlooked or neglected when the pump is used.

Pumps, when in use at all, are usually 7o worked at short intervalsthrough the day, so that foul air will not have time to accumulateduring the day, and it is the practice in the morning ordinarily to pumpout considerable water before drawing any for use. This would also freethe well of the foul air, and consequently the water used would bealways free from bad or foul air, which obviously is desirable. 1

It is obvious that the form of the air-cylinder may be modified also,that where so de sired a bellows or other suitable air-purifying devicecould be substituted therefor and connected with the. pump-handle, soits operation would be simultaneous with the act of pumping, though Iprefer the devices shown and before described.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s

1. The combination, in a pump substantially as described and shown, ofthe stock, the sucker arranged therein, the sucker-rod, the handle, theair-cylinder arranged alongside the pump-stock, and provided with a tubeextended into the well, a piston arranged in the air-cylinder, a rodconnecting the piston and the pump-handle, and the escapepipe, arrangedsubstantially as described, with its lower end opening into the well andits up- 100 a I In testimony whereof I affix my signature in presence oftwo witnesses.
